Create gae2django and rietveld clone

[matze]

In order to ensure the availability of the Rietveld source for our infrastructure, we have to clone the upstream repositories at ​https://github.com/andialbrecht/django-gae2django and ​https://github.com/rietveld-codereview/rietveld into ​https://hg.adblockplus.org/gae2django and ​https://hg.adblockplus.org/rietveld respectively - ideally prior to migrating to our own instance.

Just realized the same should be done for ​https://code.google.com/p/django-gae2django/ as well. There's no need for an explicit ticket, this can be done in the context of this very issue here.

Repositories have been created, initial commits have been made:

• gae2django: ​https://hg.adblockplus.org/gae2django/rev/9efe40071974
• rietveld: ​https://hg.adblockplus.org/rietveld/rev/13f1b9fe5615

For documentation purpose:

It seems like gae2django ​has been discontinued in May 2012. Thus, recent versions of rietveld cannot be used. In particular, I have found two major issues that reoccur at installation time:

• The patch-files in gae2django/examples/rietveld/patches fail to apply. Especially patches for rietveld template-files are a problem, because here the most changes have been applied in the last years.
• Some symbols provided by the Google AppEngine and used by rietveld are not available, e.g. {google,gaeapi}.appengine.db.StringListProperty. In fact there are even rietveld versions prior to 2012 that use this class, so this has been a missing feature in gae2django before.

I've nailed it down to 214 versions of rietveld where none of the above issues occur (according to shell-foo, I have not tested them all). The most recent of those is from November 2012. There've been a few minor issues, like missing variables in the settings.py file, but those could easily get solved (see the codereview later).
